6 month old DS has been ill last week. Seems better now but sleep is awful and he is not happy generally. Less smiley,crying a lot unless walked around. He was up screaming last night and as with the last week of nights, there was an hour or so when he just wouldn't settle, not even in bed with me, not upright on me and would start feeding then scream. I realised that just before he got ill we had gradually swapped over from Aptamil to Mamia from Aldi. Now wondering if it's this that's the issue as he is just as unsettled now he's better. Anyone else? I don't want to keep switching about particularly as Aptamil have just changed thier formula but if it's the milk then obviously need to change.
